Paintball is a sporting activity between two teams whose players are equipped with protective masks, clothes, and weapons. Weapons fire pressurized paint, or CO2 paintballs of 0.68, 0.50, 0.43, or 0.40 caliber. In the sports version, two teams of 7, 5 or 3 players fight to retrieve the flag at the opponent's base, to bring it back to its base in a limited time, located in the opposite camp. A player is eliminated when he is hit by a ball. It is a really fun game that makes you feel like you are in a war and ignites your enthusiasm.
